Care at a glance
Species-specific aquarium care
- Tank: At least 30 in long and 12 in front to back for one adult (adults commonly reach about 5.9 in / 15 cm).
- Water: Freshwater.
- Temperature: 73–77°F (range recorded for this species).
- Layout: Uses both the bottom and open water: give open swimming space plus cover near the substrate.
- Diet: A predator: feed meaty foods sized to its mouth (frozen fish, shrimp, worms); it will eat tankmates that fit in its mouth. FishBase classes it as a carnivore.
Calculated from this species' own FishBase record: tank size from its typical adult length and swimming zone, water values from its recorded ranges. The group guide below fills in general care.
Care guide
Species care notes
- Tank: a base of at least 35 × 15 in (roughly 27 US gallons); space needed is rated “large tank”.
- Water: hard, alkaline water, 73–81 °F, pH 7.5–9, 8–25 dGH.
- Behaviour: temperament territorial.
- Difficulty: Moderate (Seriously Fish rating).
Short excerpts from the species profile:
- Setup: “Should be housed in a Lake Tanganyika biotope setup, with piles of rocks arranged to form caves filling much of the aquarium.”
- Diet: “Most live and frozen foods are readily accepted.”
- Tankmates: “Although it is a territorial species, it is generally peaceful towards fish it can't fit into its mouth and is a good addition to a Tanganyikan community.”

Lake Tanganyika cichlids
Applies to most species in this group. Habitat: Rocky reefs, shell beds and sand of Lake Tanganyika. Individual species can differ, so compare with the species numbers above and the linked sources.
Housing & setup
- Use species-specific alkaline-water parameters and stable, well-oxygenated conditions. For N. multifasciatus, Seriously Fish gives pH 7.5–9.0 and general hardness 8–25 dGH.
- Shell-dwellers need beds of empty snail shells; rock-dwellers like Julidochromis need stacked rockwork; Tropheus need large groups and spacious tanks.
Climate & lighting
| Water | 76–81°F |
Diet
- Tropheus moorii needs a vegetable-based staple with small suitable live/frozen supplements. Other Tanganyikans need their own feeding plan; shell-dweller and predator diets differ.
Social life
- Often pair- or colony-forming and territorial; research each genus.
Health watch
- Tropheus are prone to bloat on rich foods; sudden water changes stress Tanganyikans.

In the wild
In the wild
From this species’ own FishBase record (habitat, bottom type, water and breeding data), not its family. Good care copies these conditions.1
| Where it lives | Lives in freshwater, in lakes. Uses both the bottom and open water. Not rock-bound, may migrate through the very shallow waters of the lake. Although the gut contents indicate a shrimp menu, this species has been known to ambush young cichlids. A substrate spawner which has often been observed to spawn in empty snail shells found on the sand floor. |
| Ground it lives on | Over rock. |
| Water it lives in | Freshwater, 73–77 °F (23–25 °C). |
| Climate | Tropical climate. |
| Wild diet | Hunting macrofauna (predator). Troph of juv./adults from 1 study. |
What this means for care
- Keep water within its wild range, 73–77 °F.
- Provide rockwork with crevices to hide in.
Native climate (measured)
Native climate (measured)
| Warm-season highs | about 87°F (up to 91°F in the hottest sampled areas) |
| Cool-season lows | about 61°F (down to 54°F in the coldest sampled areas) |
| Average temperature | 69–81°F across sampled records |
| Relative humidity | 54–66% on average (driest month about 47%) |
| Rainfall | about 992 mm a year, with strong wet and dry seasons |
Measured at 24 wild occurrence records sampled against WorldClim 2.1 climate data (1970–2000 averages). Air conditions in the range are ecological context, not enclosure settings: microhabitats such as burrows, leaf litter or basking rocks can be cooler, warmer or more humid.
